Device for simultaneously detecting front and back surfaces of workpiece

Abstract

The invention discloses a device for simultaneously detecting front and back surfaces of a workpiece. The device comprises an orbital transportation mechanism, an upper X and Y movement mechanism, a lower X and Y movement mechanism, an upper camera detection mechanism, a lower camera detection mechanism and a support installation mechanism. The upper X and Y movement mechanism, the orbital transportation mechanism and the lower X and Y movement mechanism are arranged from top to bottom and can move individually. The upper camera detection mechanism and the lower camera detection mechanism are respectively arranged on the upper X and Y movement mechanism and the lower X and Y movement mechanism. A workpiece is arranged on the orbital transportation mechanism. The upper X and Y movement mechanism and the lower X and Y movement mechanism can realize X and Y direction movement and thus front and back surfaces of the workpiece are simultaneously detected, operation is flexible and changeable, detection efficiency of an optical detection apparatus is improved and multitime detection errors are reduced.

Description

technical field [0001] The invention belongs to an optical detection instrument, in particular to an optical detection device capable of realizing double-sided detection of an object. Used in optical detectors in the printed circuit board industry and surface mount technology production. Background technique [0002] In the current printed circuit board industry (referred to as PCB) and surface mount technology (referred to as SMT) in the production of optical detectors (abbreviated as AOI), most of them use a set of independent X and Y direction motion mechanisms, and a set of independent The advanced camera inspection mechanism, combined with AOI inspection software, performs single-sided inspection of the front or back of the workpiece. The workpiece is transported to the position to be detected through the conveying track. After the sensor detects that the workpiece is in place through the AOI detection software control sensor, the fixture mechanism starts to move and f...

AI Technical Summary

Problems solved by technology

[0003] A set of independent X, Y movement mechanism, a set of independent camera detection mechanism, can only detect one side of the front or back of the workpiece at the same time, and cannot detect the front and back of the workpiece at the same time

However, in the PCB industry, it is necessary to detect both sides of the workpiece. A set of independent X and Y motion mechanisms and a set of independent camera detection mechanisms can only detect one side first and then the other side. The efficiency is low and the detection error Large, high production costs, to a certain extent restrict the automation and intelligent development of the PCB industry
